Carbonated-ferruginous-bath composition.



To all whom it may concern:

Be it known that I, ALFRED ZUOKER, a

UNITED STATES PATENT omen ALFRED ZUGKER, or DRESDEN, ennmunassleuon T0 MAX ELB, GESELLSCHAFT MIT BEscnRANKTER HAFTUNG, or DRESDEN, GERMANY.

CARBONATED-FERRUGINOUS-BATH comrosn'rou.

subject of the King of Bavaria, and resident of 63 Schnorr street, Dresden, in the Kingdom of Saxony, German Em ire, have invented certain new and useful mprovernents in Carbonated-Ferruginous-Bath Compositions. I i

- This invention relates to a composition for carbonated ferruginous baths and to an imroved method of producing the same. It

as already been proposed to prepare such baths by adding an iron com ound such as ferrous sulfate or iron chlori( It has alsobeen proposed to form a bath composition of this nature by adding sufficient acid to. the

water in order both to neutralize the bicarbonate and to dissolvean organic salt'of iron.

The novelty of the present invention consists in dissolving an organic compound for instance albuminate of iron in thebath water,

Such an organic compound is not decomposed even either by carbonic acid or by the icarbonate of soda. The organic compound may be dissolved se arately and'th'e-so ution be added 'to the bat or the said or anic compound of iron may be mixed wit the acid used or with the bicarbonate and the substances then added to the bath. Convenient proportions to use are as follows :potassium bicarbonate 600 parts, formic acid 350 parts, albuminate of iron 5 arts. The ferric albuminate is first dissolve in the water and Specification of Letters Patent.

Application filed October 7, 1907. Serial No. 396,298.

Patented Dec. 29, 1908,

then the formic acid is added after which the potassium bicarbonate is inserted.

It will be understood that the quantity of the above mixture employed in an ordinary house bath may be. varied within wide limits according to the strength of bath re uired. Thus for an ordinary house bath hal filled with Water the quantity employed may be from 1% ounds upwards. It Wili be understood hat instead vof potassium bicarbonate sodium bicarbonate may .be employed in the above formula.

I claim':

1. The hereindescribed rocess of forming a ferruginous carbonated ath-com osition, consisting in forming an a ueous so ution of albuminate of iron, mixing orrnic acid therewith and finally dissolving in the resulting solution a quantity of an alkaline bicarbonate, substantially as described.

2. The hereindescribed process of forming a ferruginous bath-com osltion consisting in forming an aqueous so ution of anorganic salt of iron, mixing an acid therewith and finally dissolviniin the resulting solution a ua'ntity of an al tially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
